Application filed March 5, 1928.

T aZZ whom it may concern Be it known that 1, DAVID (J. Eecnn'r, citizenof the United States, residing at Kennett, in the county of Dunklin andState of Missouri, have invented new and useful Improvements in Gauges,of which the following is a specification.

This invention relates to gauges and has for its object the provision ofa device adapt ed for use by carpenters in marking window jambs so as toindicate the exact points at which holes should be bored for forming thepulley openings.

An important object is the provision of a device of this character whichis adjustable whereby it may be used for marking the holes to be boredfor the accommodation of pulleys, regardless oi? whether wide or narrowsashes are to be used, the construct on being such that when the partsare adjust ed and the device is subsequently given a slight blow with ahammer, the proper marks will be made upon the window j amb.

An additional object is the provision of a. device of this characterwhich will be simple and inexpensive in manufacture, highly officient inuse, durable in service, and a general improvement in the art.

With the above and other objects and a dvantages in view, the inventionconsists i. the details of construction to be hereinaitcr more fullydescribed and claimed, and illustrated in the accompanying drawings inwhich Figure l is a sectional view through a portion of a window jambshowing my device associated therewith and in contracted position,

Figure 2 is a side elevation,

Figure 3 is a cross sectional view showing the adjustable members movedoutwardly to their maximum degree,

Figure 4 is a. plan view,

Figure 5 is a perspective view of one of the movable members, and

Figure 6 is a detail plan view of the movable members removed.

Referrin more particularly to the drawings, the letter A designates awindow jamb which it is desired to mark for the boring of the holes informing the pulley openings. Tn carrying out my invention 1 provide abody 10 which may be formed as a casting and this body is rectangular inform and provided centrally of its top with a projee tion 11 andlongitudinally and centrally of Specification of Letters Patent.

its bottom with rib 12. This rib is adapted to be inserted within atransverse recess B in the jamb A. The body 10 has formed therein spacedparallel cylindrical holes 13 and is provided in its top with a pair ofthreaded holes 14: leading into the holes 13.

Associated with each side of the body 10 is a plate 15 which has itslower edge formed to provide a plurality of penetrating prongs or tinesl6 and it will be observed that these plates 15 are of the same lengthas the body 10 and of such height or width with respect thereto that theprongs or tines 16 will extend beyond the adjacent face of the body. Theplates 15 each carry cylindrical studs 17 and 18, the former beinglonger than the latter and the studs on. one plate are ar ranged thereverse of those on the other plate, that is the long and short studsare in alternation. These studs 17 and 18 extend into the holes 13 andare engaged by set screws 19 threaded into the holes 1%.

In the use of the device, the body is so placed that the rib 12 thereonwill be disposed within the groove B provided for the reception oi theparting strip. The set screws 19 are loosened and the plates 15 aremoved away from or toward the sides 01" the body a suiiicient degree sothat the distance between the plates will be the distance between thecenters of the pulleys, and this of course depends entirely upon thethickness of the sash. The device being thus positioned and the plates15 being thus adjusted and the set screws 19 tightened, the operatorstrikes a light blow with a hammer or other implenett, upon theextension or projection 11 whereupon the penetrating prongs or tines 16will be driven into the j amb and will indicate the centers of holes tobe bored by a brace and bit in forming the pulley receiving slots. Thedevice is then of course removed JTODI the window jamb and it will befound that each plate or rather the penetrating prongs thereon has leftfour indentations in the face of the jamb and when holes oi? properdiameter are bored with these points their centers the pulley receivingslots will be formed.

From the foregoing description and a study of the drmvings it will beapparent that I ha ve thus provided a very simply constructed and easilyset and operated device whereby the necessary markings for pulley slotsmay be quickly, easily, and accurately made, the device thereby being agreat labor saver besides improving the quality of the work by making itaccurate.

While I have shown and described the preferred embodiment of myinvention, it is of course to be understood that I reserve the right tomake such changes in the form, construction, and arrangement of parts aswill not depart from the spirit of the invention or the scope of thesubjoined claim.

Having thus described my invention, I claim:

A device otthe character described comprising a rectangular body havingformed upon its underside a longitudinally extending central rib adaptedfor engagement within the parting strip receiving groove of a windowjamb, said body being provided upon its upper side with an impactreceiving projection, said body being further vprovided with spacedparallel holes extending entirely therethrough from side to side, aplate disposed at each side of the body and having one edge formed witha plurality of spaced penetrating points, studs carried by said platesand slidably engaged within said holes whereby the position of saidplates may be varied with respect to their distance from the sides ofthe body, and screws threaded into the body and engaging said studs forholding said plates in adjusted positions.

In testimony whereof I aflix my signature.

DAVID GARILE EGBERT.
